Join me for a pic-heavy stroll through MACNA 2014. My camera battery was charged and my belly full from the wonderful fare of Denver, Colorado. It took all I had as MACNA was dense with new products, great speakers and more than a few frags. You might want to sit down. Here come 78 photos in the first installment of the 3reef MACNA 2014 series.

Did you see this? Incredible. A nearly 5 foot nurse shark caught on a fisherman's line becomes the unintended bait for a monster goliath grouper that takes it in one bite. Repeat: A nearly 5 foot shark in one bite! One would think if a goliath grouper could take out a shark they would be the kings of all they survey, but they themselves have been fished to near extinction earning protected status. The goliaths are on the rebound in south west Florida where remaining mangroves protect their young. But pressure is mounting to repeal their protection. That would be unfortunate for fish that can grow nearly 8 feet long, weigh 680 pounds and eat a sizable shark... in one bite.

Move over ocean-life, here comes the Supersonic Submarine. A team of Chinese scientists recently said they have created a fluid sub design that can create an air bubble around the sub allowing it to travel at a much higher rate of speed with less friction. Apparently this is the 'drag car' of underwater propulsion - supercavitation - the Soviets developed it for torpedoes. They go fast in a straight line. But the Chinese scientist at Harbin have come up with a way to steer by altering the cavitation bubble with liquid on the exterior that creates friction. Just read it. Sounds like a dangerous thing to test out - and not just for the local fish. But so is drag racing.

The CAD Lights Aquariums new PLS-50 Elite protein skimmer truly is the "cutting edge of nano protein skimming" in that it is really small. So small with little details that when I pulled it out of the box I thought I was looking at a 1/10 scale protein skimmer model. I was not prepared for this. Somehow in the marketing details I missed the part that said "by removing the control pipes, valves, wedges etc. we have reduced the size by 40%." Indeed they have. And I'm not sure why. The 1st generation PLS-50 had a radically small footprint allowing for sump positioning, yet the skimmer itself was nearly average size. That was the genius of it even with its water line stability issue. In my mind that was all they needed to address with this updated version. But Cad Lights had other ambitions with the PLS-50 Elite by putting the 'nano' in nano. Read on for how it performs.
